Galactic winds from star-forming galaxies are crucial to the process of galaxy formation and evolution, regulating star formation, shaping the stellar mass function and the mass-metallicity relation, and enriching the intergalactic medium with metals. The multi-phase galactic winds associated with stellar feedback may be driven by overlapping supernova explosions, the radiation pressure of starlight on dust grains, and cosmic rays. The growing observations of cold molecular, cool atomic, ionized warm, and hot outflowing gas in a large number of galaxies are not completely understood. I summarize the possible mechanisms associated with stars to launch galactic winds and review the multidimensional hydrodynamic, radiation hydrodynamic, and magnetohydrodynamic simulations of winds based on various algorithms. Theoretical challenges and future research directions are also discussed. View this paper
